MACHINE FOR WINDING BOBBINS FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 377,542 dated February7, 1888 Application filed August 10, 1887. I Serial No. 246,584. (somodel.)

To all whom it may concern:

Be it known that I, GEORGE HENRY WIL- LEY, of Abington, in the county ofPlymouth and State of Massachusetts, have invented a new and usefulImprovement in Machines for Winding Bobbins for 'Sewing- Machines, ofwhich the following is a full, clear, and exact description.

This invention relates to machines for wind- I ing thread on the bobbinsof the Wheeler & Wilson,the Singer, and other scwing-machines inshoe-shops and elsewhere; and it consists in certain novel constructionsand combinations of parts, substantially as hereinafter described, andpointed out inthe claims, the whole constituting a machine which is verysimple,and

.3 is a vertical section, on a larger scale, upon the line a w in Fig.2, showing certain details only; and Fig. 4 is a horizontal sect-ionupon the line 3 y in Fig. 3.

A is the body or frame of the machine, which may be secured upon a benchor table, B, for

operation by means of a treadle, O,which sets in motion, through apitman and crank or wrist-pin connection, as shown in Fig. 1, a drivingpulley, D, that through an endless band, b, and second pulleyE rotatesthe one spindle or mandrel, F, of the winder. The band I) may either bea straight or crossed one, according to the direction it is required torun the winder.

In the same axial line as the spindle F is another shaft or spindle, G,which is not only capable of rotation, but also, unlike the spindle F,of being moved longitudinally toward or from the spindle F. Upon theinner ends of these spindles F and G, which have their bearings upon theframe A at suitable distances apart, are secured circular heads or disksH H, that serve to hold the bobbin I between them while winding, arubber facing, 0, upon each disk H serving to keep the bobbin fromgrooves g screw, t.

slipping and from falling out while winding.

Pressure is applied to the outer end of the spin dle G to keep thebobbin in position'while winding. This is done mainly by a bell-cranklever, J, pivoted to the main frame at d and controlled in part'by aspring, K, that operates to keep the spindle G pressed forward.

L is a bell-crank lever beneath the bench or table top, arranged in suchlateralrelation to the treadle O that the operator while sitting canpress with his left knee on said lever while the foot of his other legis applied to working the treadle, thus leaving his hands free forputting the bobbin in and out and for feeding or controlling the threadto the bobbin. The one arm of this lever L is connected by a rod orwire, 6, with the bell-crank J, and when the operator presses his kneeto the left against said lever L the outer upright arm of the bell-crankJ is moved in the same direction against the tension of the spring K.This movement causes the spindle G to be slid back for the purpose ofputting in the bobbinor takingit out, the sliding of spindle G beingeffected by a bent wire shifter, M, made to straddle a grooved portion,

f, of the spindle G and connected with the bell;

crank grooves g g in a projection on the face of the upper arm of thebell-crank or lever J, the legs I of said shifter M being held,withfreedom to slide longitudinally, if desired, within the This makes avery simple shifter attachment that may be readily taken out or replacedwhen necessary.

The bell-crank lever J has its movement restricted in either directionby means of stops k k or otherwise.

The bobbin ,1 being in position in the machine, the operator presses thethread onto or over itwhile he works the treadle with his one foot towind the thread onto the bobbin, his left knee then being inoperativeagainst the lever L.

The bobbin holders or disks H H are some- J by fitting it down within orthrough g by a face-plate, h, secured bya what smaller on their facesthan the heads of the bobbin to facilitate the taking of thebobbin fromthe winder by the finger and thumb after the thread has been wound onit. Said holders or disks H H, too, are of conical form on theirperipheries, converging toward one another. The object of this is,incase the operator should fill the bobbin too full of thread, some of thethread would be wound on the disk or disks H H,which, by reason of theirbeveled exterior;would cause the thread to lie close to the bobbin, sothat when taking the bobbin out of the machine the thread would slidetoward the center and come out all straight. \Vere the bobbinholders H Hbeveled in a reverse direction, or were they simply flat thin disks, thethread would wind upon the spindles on either side in case the bobbingot too full.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. The combination, with the frame or body A,of the rotatable spindle F, prodded with a disklike bobbin-holder on itsinner end, the rotatable and longitudinally-sliding spindle G, having acorresponding bobbin-holder on its inner end, the lever J, connectedwith said spindle G, a spring applied to said lever operating to forceup or inward said spindle'G, the lever L, connected with the lever J andadapted to be controlled by the knee of the operator, and the treadleO,with connected devices for rotating the spindle F,essentially asdescribed. 2. The combination, with the rotating andlongituclinally-sliding spindle G, of the lever J, and thespindle-shifter M, fitted to slide Within or through grooves in saidlever and to straddle and engage with said spindle, and the removableface-plate h, essentially as shown and described.
